Art critic Alastair Sooke tracks down the ten most expensive paintings to sell at auction, and investigates the stories behind the astronomic prices art can reach. Gaining access to the glittering world of the super-rich, Sooke discovers why the planet's richest people want to spend their millions on art. Featuring works by Picasso, Monet, Renoir, Van Gogh, Klimt and Rubens, Sooke enters a world of secrecy and rivalry, passion and power. Highlights include a visit to the art-crammed home of millionaire author Lord Archer; a rare interview with the man at the heart of the sale of the most expensive old master of all time; privileged access to auctioneers Christie's; and a glimpse of the world of the Russian oligarchs. These revelatory journeys allow Sooke to present an eye-opening view of the super wealthy, and their motivations as collectors of the world's great art treasures.
